These branded, engineered gaskets provide a cost-effective, reliable, and easy to use alternative to tacky-cloth, spiral wound and expanded PTFE gaskets. Black Max gaskets can be used as a cost-effective sealing alternative in most types of higher pressure industrial vessels and tanks that have inspection openings. The proprietary graphite used to manufacture these gaskets gives them exceptional thermal stability combined with chemical inertness, ensuring superior service capability under simultaneous conditions of saturated and superheated steam. They provide boiler manufacturers, users and service companies handhole and manhole gaskets with unprecedented characteristics. Compared to spiral wound gaskets, Black Max gaskets are compressible enough to conform to the topography of the mating surfaces – even on old worn and pitted flanges – with less torque. Their recovery characteristics are also superior to spiral wound gaskets and they are significantly lighter than spiral wound products. Black Max gaskets are easy to remove and replace with no chiseling or buffing required. Sizes are clearly marked on each gasket for easier identification.
